At least three people including two retired policemen have been killed after a passenger bus crashed into the mountainside along a pass in the south-central Vietnamese province of Khanh Hoa.

The accident occurred at around 9:00 am on Saturday along Khanh Le Pass, which connects Khanh Hoa Province and the Central Highlands province of Lam Dong.

The passenger bus was carrying 31 people who were retired police officials and their family members from Luc Yen District in the northern province of Yen Bai for a vacation.

According to their travel itinerary, the group of visitors had just visited Da Lat, a tourist city in Lam Dong, and was heading to the beach city of Nha Trang in Khanh Hoa.
